Hi Mark, (...) is it really true that there is a square law for PWM? Can you explain the reason why this is so? I understand that this is true if you change the voltage (half the voltage gives half the current so a quarter of the power). But I (...)

(...) That sounds like the datalog indicator - while RIS doesn't take advantage of it (to my knowledge), the RCX can function as a datalogger - the quarter of the datalog that is being loaded flashes, while the quarters of the datalog that are (...)

I am not sure here - but could that mean that the batteries are seriously low? It would seem likely if they have been sat for a while, as even when powered down there is some residual current usage, and leakage in the RCX. Remember that when (...)

G'day, I have been using my RCX 2.0 brick recently after it has been laying idle for a period. I have noticed that there is an extra icon in the display window which is not discussed in the Lego Robotics Invention System 2.0 Constructopedia. I was (...)

(...) Firmware is the Operating System for the RCX, the way Windows (or whatever) is the OS for your PC. Firmware by itself doesn't do anything, it's just there to run the programs that you write.
